Yes, I know that I was banned for plagiarism, but I saw plagiarism from other users and felt that it was allowed on the forum. But I will delete all messages with plagiarism and will not break any more rules! Please unlock!
Not knowing the rules isn't a valid excuse. It doesn't matter what you felt.
Plagiarism is a straight permaban with no chances of unban. You can cry, yell or tell that you won't do it again all day... it doesn't matter. Your account won't be unbanned.
P.S: Keep in mind that YOU (as a person - and not only your account) is permabanned from the forum. You can't create a new account to keep posting. You should just leave the forum or else you will be banned again for ban evasion.
